Ansible For Networking Part 2
Convert playbook from part 1 to Ansible roles.Ansible For Networking Part 2
This is part two of a series on Anisble for network engineers. In this part of the series we will take the playbook from part one and convert it into roles. Roles in Ansible allow for easy re-use and sharing of code and it is important to understand them as they will use role based...Turkiyede CCDE Egitimi
Bu Turkce paylastigim ilk post olacak. Heyecanliyim. Ama daha cok , Turkiyede ve Turkce CCDE Egitimi verecek olmaktan dolayi heyecanliyim. Takipcilerim bilirlerki 2 yildan fazla bir suredir Cisco CCDE Egitimi vermekteyim ve egitimlerime Dunyanin her yerinden 100 lerce kisi katilmistir. Cogunlukla Online/Live olmakla birlikte, Amerikada, Dubai de , Afrika da , Qatar ve Avrupada Onsite […]

MPLS Layer 3 VPN Deployment
MPLS Layer 3 VPN Deployment In this post I will explain MPLS Layer 3 VPN deployment by providing a case study. This deployment mainly will be for green field environment where you deploy network nodes and protocols from scratch. This post doesn’t cover migration from Legacy transport mechanisms such as ATM and Frame Relay migration as […]

Ansible For Networking Part 1
Build a spine/leaf network with Ansible and Cumulus.Ansible For Networking Part 1
This is part one of a series on Anisble for network engineers. The series will concentrate on Ansible as a configuration management tool for networking and is aimed at those with a basic understanding of Ansible. If you are just starting out with Ansible, see my quick start guide here and...MPLS Transport Profile (MPLS-TP) Basic Explanation and Key Points
MPLS Transport Profile (MPLS-TP) Multi-Protocol Label Switching Transport Profile (MPLS-TP) is a new technology developed jointly by the ITU-T and the IETF. The key motivation is to add OAM functionality to MPLS in order to monitor each packet and thus enable MPLS-TP to operate as a transport network protocol. Motivations for MPLS Transport Profile […]

The Internet’s Gilded Age
The rise of the Internet has heralded rapid changes in our society. The opportunities presented by a capable and ubiquitous communications system and a global transportation network have taken some corporations from the multinational to the status of truly global mega-corporation. There are a handful of large scale winners in this space and many losers. But this is not the first time we’ve witnessed a period of rapid technological and social change.White Box Switches Have Grown Up
White box switches have come a long way. The recent activities in OCP validate the vision and progress of white box switches, and more importantly it is clear that this trend is progressing from data centers to enterprises. I remember when Zeus Kerravala wrote in his 2016 article, “White Box Switches are Now Ready for Prime Time,” he pointed out three important advantages:
– Cost and reliability
– Features and capabilities
– Network operations
As a NOS vendor, we see NOS is being adopted into production environments. Even though there are still challenges with white box switches going from data centers to other segments, there is no doubt the networking industry has moved onto the path toward white box switches.
From what we saw at OCP Summit, the overall reliability of white box switches is improving, and in many cases, they are more reliable than some brand-name hardware. We can now find dozens of vendors providing white box switches. These vendors come with different backgrounds and carry out different approaches in designing their hardware platforms. In OCP, we can see three clearly different types of vendors providing white box switches:
- Brand name vendors, such as HPE and Dell. This group Continue reading
